<em>Comment on equal sign</em>

IMO, one should never use an equal sign where things are not equal--unless there is a clear indication you understand they are not equal. The equal sign should be regarded as a sacred symbol, with very specific rules as to its meaning and use.

Find the value of this expression if x=9 x2 + 6 / x - 6
GREYUIT [131]

Answer:

87/3

Step-by-step explanation:

Here we are given the expression:

\frac{x^{2}+6}{x-6}

Now we have to find the value of this expression when x equals 9.

So plugging the value of x as -9 in the given expression:

\frac{x^{2}+6}{x-6}

=\frac{(9)^{2}+6}{9-6}

=87/3

So on evaluating we get the value of expression as 87/3.

Christine is 4 years younger than Mark. 3 years from now, she will be two-thirds as old as Mark find their present ages.Complete
icang [17]

Answer:Mark Is 9 years old; Christine is 5 years old

Step-by-step explanation:

Present age

LET  mark age be x

Christine be x-4 yrs

In 3 yrs Time

Mark will be x+3 yrs old

Christine  will be  (x -4 +3) = x-1 years old

Also, In 3 years time

Christine  = 2/3 Mark

such that

  x-1 = 2/3(x+3)

  x -1= 2x+6 / 3

    3x  -3= 2x+6

      3X--2X = 6+3

         =X=9

Mark Is 9 years old

Christine is   x -4 = 9-4=5 years old
